Radiological Investigation III: Pulmonary Angiogram and PET Scan

92
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Summary

Prostatic artery embolization (PAE) is effective for benign prostatic hyperplasia, but radiation exposure is a concern. This study found no 90-day adverse events related to radiation, with median effective doses of 17.8 mSv (fixed units) and 12.3 mSv (mobile units).

Area of Science:

  • Interventional Radiology
  • Medical Imaging
  • Radiation Oncology

Background:

  • Prostatic artery embolization (PAE) is a minimally invasive treatment for benign prostatic hyperplasia.
  • Understanding PAE's patient radiation exposure and risks is crucial.

Purpose of the Study:

  • Quantify radiation dose in patients undergoing PAE.
  • Assess radiation-related adverse events following PAE.

Main Methods:

  • Retrospective study of 1476 patients across 10 international centers (2014-2021).
  • Calculated effective radiation doses using kerma-area product and conversion factors.
  • Assessed correlations between dose and patient/procedural factors using regression analysis.

Main Results:

  • Median effective dose was 17.8 mSv for fixed and 12.3 mSv for mobile fluoroscopy units.
  • Radiation dose positively correlated with body mass index and fluoroscopy time.
  • No radiation-related 90-day adverse events were reported.

Conclusions:

  • PAE radiation doses vary by fluoroscopy unit type.
  • No short-term adverse events linked to radiation exposure were observed.
